Application filed September 13, 1918.

new and useful Improvements in Battle Plates for V-Type Motors, of which I declarethe following to be a full, clear, and exact description.

This invention relates to internal combustion engines and has for its object to provide means to control the amount of 011 delivered to the engine cylinder or the sur-' face within which the piston operates. Although not limited thereto, the invention has particular utility in connection wlth V- type motors in which the cylinders are located at an angle, in which position not only is more oil received, being thrown, splashed or carried up by the rotating elements of the engine than in the case of an up-rlghtcylinder, but the inclination of the cylinders also tends to retard the return flow of any excessive oil into the crank casing. It

is to be understood, however, that the con trolling means employed herein may be used with vertically arranged cylinders, as well as with V-type motors.

By my invention I provide means operat ing to deflect a portion of the oil which would otherwise enter the cylinder, 1t being also an object of my invention to so arrange such means as to permit the oil received by the surface within which the piston works to drain back into the casing. It is apparent that such means may be supported and carried into the proper place by any suitable mechanical expedients.

Futher objects of this invention relate t the details of construction, arrangement of parts, and the association of the elements disclosed herein as illustrating one means for carrying the invention into effect.

Referring to the drawings, Figure l is a sectional view of a V-type Knight motor with my invention connected therewith.

Figure II is a section through a portion of a V -type motor with poppet valves showing my invention applied thereto.

Figure III is a bottom plan view of the type of baffle plate illustrated herein as one efficient means effective for the purposes herein intended.

Figure IV is a sectional IV-IV of Figure III.

Referring to Figure I, there is shown within the crank casinglO the usual crank shaft 11 connected to the piston rod 12 bv the assembly 18, the lower portion of the crank shaft casing 10 being provided with an o1l pan 15 adapted to contain oil to a suf ficient level so that the rotation of the crank shaft effects a splashing of the oil up into the engine cylinders to lubricate the engaging surfaces between the engine piston and the cylinder within which the same operates.

In Figure I the piston 20 is shown within the inner sleeve or movable cylinder 21 of the well-known type of a sliding sleeve valve motor, and interposed between the sleeve 21 which constitutes a moving cylinder for the view on the line piston 20 and the rotating crank shaft 11 is located any type of baffle means 23 for deflecting a portion of the oil delivered thereto.

The bafiie 23 may be supported from any desired portion of the engine construction. I have found that a convenient location of support for the baffle 23 is on the lower end of the sleeve or cylinder 21. The batlle 23 in the particular embodiment shown herein consists in a plurality of plates 25 and 26, each provided with elongated slots 27 and 28, each slot having an enlarged portion 29 and narrow portion 29. The lower end of the sleeve or cylinder'Ql is provided with a plurality of studs 30, one for each of the slots 27 and of each of the plates. The studs 30 may have a hexagonal central portion 31 to facilitate the application of a wrench in screwing the same into the end of the cylinder 21, a reduced neck portion 32 and an outer head 33. The heads 33 of each of the studs 30 are of a size to pass through the enlarged end 29 of the openings 27 and 28 when the battle is inserted thereon, while the reduced portion 32 slides in the narrow portions of the slots 29' with the heads of the studs overlapping the lower surface of the batlle plates 25 and 26, to thus support t io studs in spaced relation from end of the cylinder or sleeve 21.

Suitable means for locking the balile plates in position may be employed, and to this end there is shown herein a leaf spring 35, located and terminating in such position as to engage the vertical side wall of the stud L lle heads 33 when the baflie plates and 26 have been inserted on the studs and slid endwise to cause the reduced portion 32 of the stud to enter the narrow portions of the slots 27 and 28. It is apparent that any other means for securing the baiiie plates 25 and 26 to any desired portion of the engine structure may be used.

The battle plate sections 25 and 26 are spaced apart to provide an opening 36 therebetween within which the piston rod operates, and through which the oil which it is desired to deliver into the cylinder may be thrown on the cylinder wall surface, the baffle plates operating to deflect a portion of the total amount of oil thrown centrifugally from the rotating crank shaft 11. he relative area of the lower end of the cylinder or sleeve 21 left open for the passage of oil, may be readily determined and the baiile plates 25 and 26 may then be made of the proper size and secured to the cylinder a proper distance apart.

As shown in Figure II, the battling means 23 may be secured to a portion of the inner surface of the crank casing 10, or the lower end of the cylinder 21.

The operation of my invention will be readily understood from the foregoing. It will be seen that there is provided means to control the amount of oil delivered to the surface within which the piston moves by interposino' a battle to deflect a portion of the oil delivered to the cylinder by a rotating element splashing the same up from the oil pan. A portion of the baii'ling means extends on both the side of approach and the side of departure of the rotating crank shaft 11 relative to the cylinder sleeve 21 and the location of the same on either side may be controlled at will, if desired, to meet the needs of the engine.

It is to be understood that this invention comprehends broadly the provision of any means for controlling the amount of lubrieating oil thrown up into the cylinder of an internal combustion engine by inter-posing means to deflect a portion of the oil so delivered and that the location of the battle or deflecting means is immaterial, it being evident that the same may be supported from any desired portion of the engine construction. It is also to be understood that any type of baffle may be employed, and, moreover, that any means for securing the same in the structure in contact with or spaced from the cylinder of the engine may be employed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. In an internal combustion engine, the combination with an open ended cylinder of means secured thereto for deflecting oil delivered to said cylinder including a. readily 2.
